desert air.

*** Ouules 4 (—6); calyx teeth similar, pod glandular-dotted, exserted;

g. PAROSELA SPINOSA Heller, Cat. N. Am. Pl. ed. 2. 7. 1900.— 
Dalea spinosa Gray, Mem. Am. Acad. 5:315. 1855; Torrey, Pac. 
R.R. Rep. 73:9. pl. 3. 1856; Asagraea spinosa Baillon, Adansonia 
9:233. 1870.—Intricately branched tree 4-7 m. high, the numer- 
ous spinescent branchlets hoary with a fine close pubescence, and 
sparsely dotted with small flat glands; leaves very few and 
promptly deciduous, narrowly oblong, the margins thickened, 5 
mm. long: flowers on pedicels 1 mm. long; calyx 5 mm. long, 
strongly nerved, encircled above with a ring of large, reddish, 
guttate glands; teeth 2 mm. long, ovate; corolla dark blue; banner 
6 mm. long and as broad; keel and wings 8 mm. long; anthers with 
an oblong red gland at base. 
The flowers do not extend to the sharp horny spine of the branchlets, not 
all of which are floriferous, and which cannot be regarded as the peduncles 
of a true spicate inflorescence. Parosela Kingii (Wats.) has solitary flowers 
borne on like spinescent branchlets, and Holécantha Emoryi Gray has an 
analogous inflorescence. 
Type.—‘‘Arroyos on the Gila; and on the California Desert west of the 
Colorado.”
